The correct answer is a) Neyyar Irrigation Canal.
The Neyyar Irrigation Canal is the longest irrigation canal in Kerala, India. It is a major source of irrigation for the state’s agricultural sector. The canal was constructed in the early 20th century and is named after the Neyyar River, which it draws its water from. The canal is about 100 kilometers long and has a capacity of 100 cubic meters per second. It irrigates over 100,000 hectares of land in the districts of Thiruvananthapuram, Kollam, and Pathanamthitta.
The Neyyar Irrigation Canal is a vital part of Kerala’s economy. It provides water for irrigation, drinking, and industrial purposes. The canal also supports a variety of wildlife, including fish, birds, and reptiles.
The other options are incorrect because they are not the longest irrigation canals in Kerala. The Malampuzha Canal is the second longest irrigation canal in Kerala, followed by the Peechi Canal and the Kuttiyadi Canal.
The Malampuzha Canal is about 80 kilometers long and irrigates over 60,000 hectares of land in the districts of Palakkad and Malappuram. The Peechi Canal is about 60 kilometers long and irrigates over 40,000 hectares of land in the districts of Thrissur and Palakkad. The Kuttiyadi Canal is about 40 kilometers long and irrigates over 20,000 hectares of land in the districts of Kozhikode and Malappuram.
